24 alternatives to Reactor Atlas
Hi HN, I'm a nuclear engineer and tech entrepreneur. After working for 3 years in the National Atomic Energy Commision (CNEA) in HPC software for nuclear simulations, I co-founded ratherlabs.com, a software company providing blockchain solutions for startups. Rather Labs business reached ~6 million usd in annual revenue in 2024; now demand is decreasing as our niche clients are using AI to launch their MVPs. Now I'm joining my scientific background with my entrepreneurial inclinations to think of problems related to the energy industry. Nuclear is experiencing a renaissance now (it was in a…

Hi all, I am not an expert in nuclear energy but I've always wondered and found it difficult to get a clear picture about the amount of nuclear stations located in a specific region. So I built this tool that shows all the nuclear plants in the world, scaled by their capacity and with indication of their status. Clustering is enabled by default and allows to see the sum potential capacity of a region. It's a fun tool for me: e.g. disable clustering, scale circle radius to 70%, go to EU, and you'll see Germany has shutdown all of the stations. Ofc it's a widely known fact, but what came to my…

Hi HN, I’m a chemical engineer and I manage logistics at a refinery down in Texas. Whenever I try to explain downstream operations to people outside the industry (including my kids), I usually get blank stares. I wanted to build something that visualizes the concepts and chemistry of a plant without completely dumbing down the science, so I put together this 5-minute browser game. Here's a simple runthrough: https://www.youtube.com/watch?v=is-moBz6upU. I pushed to get through a full product pathway to show the V-804 replay. I am not a software developer by trade, so I relied…

Hey Everybody! Hope you had a merry christmas Today I had a bit of fun with Claude. Started by scraping YC's startups list, then ran them through OpenAI's embedding service, then UMAP'd the embedding to reduce the dimension to just two coordinates and then just forced Claude to write React that would compile to visualize that. I had fun and I think it's interesting, so take a look! Also note that you won't be able to zoom on mobile (found about this Plotly limitation way too late). If there's interest I can fix this issue by changing plotting libs tomorrow :) Merry christmas

Hello, I wanted to share with you all a interactive map of the economics and physics constraints of the AI buildout. It has macro drivers, industrial chokepoints, and where that shows up in markets. I've added 393 nodes and 562 edges to capture other supply / physics constraints as well. There's no sign up, and no pay wall, it's all free. Please let me know what you think!

Hi HN. My name is Andrey. On a regular business day, I'm a software engineer working at AWS. Outside of work hours, I spend time on my hobby - writing code. I was once building a pet project that allowed customers to spin up fully synchronized blockchain nodes within just a few minutes. The backend was split into a control plane and a data plane, each with its own AWS account. Later I added two more AWS accounts. One for shared RPC nodes. One for the Analytics Service. Since I love to visualize things, I used drawio to visualize the architecture. With time, I noticed a pattern. I'd write…

Wow, half a year has passed since my last blog. I have to admit, during this period I was a bit disconnected from the physical AI world. I transitioned to a different team at work after their two data scientists were reassigned to other teams, and I had to ramp up quickly to take over…

TLDR: I made a community where you can find builders or product owners to collab on sideprojects together with <3 A year ago i completed my first sideproject, a digital course on how to "cold email a chief information security officer". I thought and think its a great course, but of course I fell into all the traps (didnt verify a need, i thought id make it and everyone would buy automatically), i tested google ads but hated nerding on that, so i decided to find a marketing person to partner up with! But i knew no one! That got me thinking how many people with relevant knowledge that isnt…

Hi HN! I made a thing and wanted to share it with the builders of HN. Problem: I’ve found it hard/impossible to stay consistent on my side projects over the years with a pretty demanding full-time job and now kids. When the job picks up, it’s too easy to drop the side project for a day, which becomes a week, which becomes months. It’s also been somewhat demotivating to build alone on the side because you only have so much time and projects take so long. In college it was easier to find people to work with. Now, not so much. Solution: I think it’ll be easier to stay motivated and…

Hey HN, After GPT-3 created waves in the tech industry, a lot of AI tools were emerging and with that, some AI website builders But the results seemed way too generic to us. It felt like the developers were rushing to catch the wave instead of building a proper tool We took our time, did months of RnD and finally came up with something better than what others in the market are doing. It’s got better design output. While it’s still in beta, I wanted to show HN what we did. Will appreciate the feedback when you guys try it out. Here is the link to signup for the beta:…

Hey HN. I'm a developer and solopreneur. Few months ago I realized I was doing the same thing over and over again: set up onboarding flow, user authentication, payments, connect a DB... So I built ExpoShip for 3 reasons: 1. Save Time and focus on what matters: building a business. 2. Avoid headaches like setting up authentication or handling in-app payments. 3. Get profitable fast. I hope this boilerplate will be as helpful to you as it is for me. Would love your feedback. Rudolfs

4 months ago, our announcement for our free, multi-node, petabyte-scale time-series database generated 200+ comments: https://news.ycombinator.com/item?id=23272992 Many commented on the Timescale License, our source-available license governing advanced features (eg multi-node). Most were positive, but some pointed out drawbacks (who says HN can't be productive!). That spurred an internal debate. Today we're happy to share an updated Timescale License with new rights, including the "right-to-repair" and "right-to-improve." And we’re doubling-down on our community, making all…

Hi HN, blockchain3d.info (http://blockchain3d.info) is a free 3D and VR Bitcoin Blockchain browser available for Windows, Android (with Google Cardboard for Virtual Reality), Linux and MacOS. The tool lets you enter a starting address or transaction, then navigate the Bitcoin network as far as you like (or as your hardware will allow, performance wise) to see inflows and outflows, all in 3D (or VR with Cardboard). Would love to hear feedback from HN folks!

Hi HN, Yesterday I live streamed myself for 6 hours building this from scratch. It’s an AI agent that uses Llama 2 (so far the 13b chat model) to generate a full react codebase from a single prompt. It had a “dev loop” that iterates on your feedback and resolves dependencies. In the end it kinda worked and I got excited so wanted to post here haha. Long story short a viewer on my discord suggested I build in of these and I just had to look into how these work (inspired by GPT Engineer and AutoGPT) I wanted to work on a more specific downstream task so I focused on web dev. Llama 2 isn’t the…

Hi, over the past few months I've been working on this project: Numax is a small Rust runtime that does three things: it runs WebAssembly modules in a sandbox, has a built-in local key-value store, and syncs everything across nodes with CRDTs and gossip. Basically, you write a wasm module, run it on two machines, and they converge (I hope !). It's a decentralized system... I hope someone finds it interesting! There's a whitepaper I've put a lot into, and I think the code isn't bad either! I believe there's still room in this world for software that's fun and well made, and while building…

Hi HN, We are researchers from ETH Zurich interested in the real-world adoption and impact of Code Agents. To measure this, we built a dashboard, scraping all public PRs on GitHub, analyzing which are created by different code agents (Codex, Jules, Copilot, Devin, etc.), and measuring their merge rates, sliced by various repository and PR characteristics. https://insights.logicstar.ai Since mid-May, we've analyzed over 10 million PRs and already found some interesting trends: Usage is high, but shallow. Agents submit ~7% of all PRs overall, but only ~1–2% on popular repos. Most…

Hi HN, Alexey from Chainstack here. We built Chainstack Self-Hosted to package everything we’ve learned from 8+ years of running blockchain nodes into a single control panel. The goal we’re building this product around is to make blockchain infrastructure boring to operate. The software is free to install. You only pay for the infrastructure you run it on. The quickest way to get hands-on with it is through the Vultr Marketplace or one of the other providers listed in the docs. The current release supports Ethereum Mainnet, Sepolia, and Hoodi with Reth + Prysm full nodes. We’ll be adding…

Hey everyone! I'm excited to share my newest side project, Atlas. Atlas is an open-source product analytics tool that sits on top of the data warehouse. You can do things like funnels, flows, and retention analysis that typically you need to pipe data to Mixpanel or Amplitude for. Under the hood, it uses dbt to run queries and is built using TypeScript, React, and NextJS. Check out the live demo at https://atlas-demo.onrender.com/ and let me know if you have questions or thoughts. Happy Atlasing!
